以一个小型公司的人员信息系统为例，用基类的指针数组来处理不同的派生类对象，从而实现拉多态性调用。使用动态数组类模板Array来代替C++预定义的数组类型。-to a small company personnel information system. use the base class pointer array to handle different types of derived objects, thereby realizing Rafah called polymorphism.

读取MapInfo的交换格式数据，采用Delphi语言，使用动态数组存储结果。-read MapInfo data exchange format, using Delphi language, the use of dynamic memory array results.

使用函数，指针实现对数组的动态查询，删除，插入，排序等功能-The use of function pointer to the array to achieve a dynamic query, delete, insert, sorting and other functions

分别用数组和链表方式实现去除文件中的重复行。先将文件内容读入一buffer,按行拆分，每行数据只取\t之前的部分。然后用二分直接插入法将不重复的字符串放入一二维数组或动态链表中。 -Respectively, be achieved using arrays and linked the file to remove duplicate rows. Content of the document read into a first buffer, split by row, each row
